REFRIGERATING APPARATUS.

Application led December 26, 1924. iSerialNo. 758,126.`

To all whom t 'may concern.:

-Be it .known that I, JosnrH W. DU-BRAKs, a citizen lof the United States, residing at 1601 Alamo Street, Houston, rllexas, have invented a certain new and useful Improvement in Refrigerating Apparatus, of which the 'following is a specification.

My invention relates to devices formaintaining `low temperatures in closed vessels for lthe `freezin and storage of confections and yfrozen 'foot s.

It is an object of the invention to provide a refrigerating chamber wherein the temperatures may be kept near 'freezm 1n a most economical manner. It is alsodesired that the Vapparatus'be adapted Ato provide a plurality of chambers all of which maybe maintained at low temperatures and yet readily Aaccessible when it is desired that they be removed. t

Referring to the drawing herewith, Fig. 1 is a central vertical section of a refrigerator embodying my invention. Fig. 2 1s a perspective view of one of the removable compartments. Fig. 3 is a top vlew m section approximately on the plane 3 -3 of Fig. 1. Fig. 4 is a top plan view with the top closed. Like numerals of reference are employed to designate like parts 1n all the views.

In constructing the device, I employ an outer tub or container 1 which may be wood or sheet metal and I have shown a cylindrical sheet metal tub with a circular' bottom 2 of wood.

Within the tub is an inner sheet metal container 3, the bottom and sides of which are spaced about equal distances from the inner face of the tub thus providing a chamber 4 between the two containers which I contemplate lilling with some good heat insulating material such as cork 5 preferably granulated. The upperr ends of the two containers are spaced apart, and the chamber between them closed, by an annu-l lar closure 6 secured firmly to the wall of the outer tub.

rllhe upper end of the inner container projects above the closure 6 and has thereon a ring 7 forming a rim overlapping the lower ring.

Above the ring 7 is a cover made up of two stationary segmental side pieces 8 between the spaced ends of which are supporting plates 9, 9, somewhat narrower in To these supports 9, 9 are hinged the doors 10, 10 shaped to close the open end of ythe container and meeting along Iagdiametrical line 11.` .Handles f12 are Vprovided for .opening the Vdoors when desired.

Within thc-container 3, andspaced therefrom, is an upright concentric wall .13, spaced from the container by a plurality of radial partitions 14, provided with openings 1:5 therein for purposes ofl air circulation.

It is .also contemplated that an innervcan or `container 16 of sheet metal will be pro vided, materially smaller than the cham-ber 17 in which it is seated. The chamber 17 will permit a receptacle for ice 18, or other refrigerating means. The container 16 will be fitted with a :cover 19 thereon.

The separate compartments between .the various radial wallsv 14 ,furnish storage for a series of holding trays or containers 20 of the form shown in Fig. 2. The said trays are segmental in shape to lit the said compartments. They have openings 21 adapted to register with the openings 15 in the partitions 14 and the inner wall is cut away from a point adjacent the lower end to the upper end. The to is closed and formed with a handle 22. hooked ange 23 engages over the upper edge 0f the wall 18 to support the tray with the lower end thereof slightly olf the bottom.

A drain pipe 24 extending through the walls vfrom the ice chamber outwardly acts to conduct liquid from the container to the outside. Opposite curved rods 25, on each side to the rear of the doors act as supports for the doors when open, as illustrated in Fig. 1.

The device thus constructed will serve as a freezer when the ice 18 is mixed with salt; and simply as a refrigerator when the salt is omitted. It will be noted that there are refrigerating compartments outside the ice chamber as well as inside the same. The same ice chamber is thus adapted to exert a refrigerating effect in both directions, thereby efecting a great economy. It has been found that the outer wall of the container 1 is not noticeably cooled in this arrangement and will not gather moisture lin warm weather, as ordinary metal refrigerators now sometimes do. It is contemplated that the trays may be employed to hold frozen dainties and confections for storage purposes and for sale. When thus used, the delpackages of confection desired and then the ceedingly eiiicient inooperation and economical in the use of ice, and will maintain low temperature for comparatively long periods.

Having thus described the invention, what l claim as new and desire to protect by Letters Patent is:

l. A refrigerating device comprising an outer tub, a cover thereon, a container in said tub7 heat insulatingl material between said tub and container, an annular ice chamber spaced within said container, radial compartments between said ice chamber and said container', and a storage compartment surrounded by said ice chamber.

2, A refrigerating device comprising an outer container having a wall of heat insulating material around the same, a central storage container, an annular rerigerating chamber surrounding said storage container and a series ot compartments between said refrigerating chamber and said outer container.

3. A device of the character described comprising spaced inner and outer concentric storage chambers with an intermediate annular retrigerating chamber between them, heat-insulated walls for said outer storage chamber, and removable compartments in said outer storage chamber having upper hooked supports thereon, said compartments being` perforated to allow air circulation therethrough.

4f. A device of the character described comprising an inner storage container, a second storage container outside of and concentric with the inner container, a refrigerating chamber between said containers, heat insulating walls surrounding said containers, and separately removable compartments in said second storage chamber.

In testimony whereof lf hereunto ailix m signature this 20thday of December, A. D. 1924. A
